  2. Turbomachinery - Wikipedia

    en.wikipedia.org/wiki/Turbomachinery

    Turbomachines may be further classified into two additional categories: those that absorb energy to increase the fluid pressure, i.e. pumps, fans, and compressors, and those that produce energy such as turbines by expanding flow to lower pressures. Of particular interest are applications which contain pumps, fans, compressors and turbines.

  3. Wells turbine - Wikipedia

    en.wikipedia.org/wiki/Wells_turbine

    7 air flow (can also be in the other direction) The Wells turbine is a low-pressure air turbine that rotates continuously in one direction independent of the direction of the air flow. Its blades feature a symmetrical airfoil with its plane of symmetry in the plane of rotation and perpendicular to the air stream.

  4. Turbine - Wikipedia

    en.wikipedia.org/wiki/Turbine

    A steam turbine with the case opened Humming of a small pneumatic turbine used in a German 1940s-vintage safety lamp. A turbine (/ ˈ t ɜːr b aɪ n / or / ˈ t ɜːr b ɪ n /) (from the Greek τύρβη, tyrbē, or Latin turbo, meaning vortex) [1] [2] is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.

  5. Gas turbine - Wikipedia

    en.wikipedia.org/wiki/Gas_turbine

    The basic operation of the gas turbine is a Brayton cycle with air as the working fluid: atmospheric air flows through the compressor that brings it to higher pressure; energy is then added by spraying fuel into the air and igniting it so that the combustion generates a high-temperature flow; this high-temperature pressurized gas enters a ...

  6. Wind-turbine aerodynamics - Wikipedia

    en.wikipedia.org/wiki/Wind-turbine_aerodynamics

    Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.

  7. Subsea technology - Wikipedia

    en.wikipedia.org/wiki/Subsea_technology

    Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power ...

  8. Air-independent propulsion - Wikipedia

    en.wikipedia.org/wiki/Air-independent_propulsion

    Specifically, a conventional steam turbine power plant is powered by steam generated from the combustion of ethanol and stored oxygen at a pressure of 60 atmospheres. This pressure-firing allows exhaust carbon dioxide to be expelled overboard at any depth without an exhaust compressor. [citation needed] Each MESMA system costs around $50–60 ...

    The losses occur in an actual turbine due to disc and bearing friction. Figure shows the energy flow diagram for the impulse stage of an axial turbine. Numbers in brackets indicate the order of energy or loss corresponding to 100 units of isentropic work (h 01 – h 03ss). Energy flow diagram for the impulse stage of an axial turbine
